Installing R and R studio on Ubuntu 12.10

Yes I know why 12.10? Well I am lazy to upgrade but also for the fact that the newer versions of Ubuntu haven't exactly set the world on fire. Anyways why am  I writing this post? Its pretty easy to install R but R studio? Well R studio wasn't willing to get installed on my PC after downloading the package.

For the uninitiated R studio is a IDE for  R and its pretty useful GUI.

So how did I manage to install R and R studio? Lets get over with some basic commands to install/update R.

To obtain the latest R packages, add an entry like

sudo add-apt-repository "deb http:///bin/linux/ubuntu saucy/"

or

sudo add-apt-repository "deb http:///bin/linux/ubuntu raring/"

or

sudo add-apt-repository "deb http:///bin/linux/ubuntu quantal/"

or

sudo add-apt-repository "deb http:///bin/linux/ubuntu precise/"

or

sudo add-apt-repository "deb http:///bin/linux/ubuntu lucid/"

But don't forget to replace by the actual URL of your favorite CRAN mirror. See http://cran.r-project.org/mirrors.html for the list of CRAN mirrors. 

To install the complete R system, use

   sudo apt-get update
   sudo apt-get install r-base

Then Install gdebi which checks for dependencies 

sudo apt-get install gdebi

Adding RStudio

Download R studio

After downloading R studio package run the following command

sudo gdebi 

Well ideally no errors should come up and you can find R studio installed and ready to fireup.
